AEG Timer / Delay Start Logic Fault

Timer or delayed start function does not work correctly; cooking starts immediately or not at all.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect user programming, Faulty real-time clock circuit, Firmware bug, Control panel input error

Safety first: No internal live work is required for basic checks; unplug before opening any covers.

Verify settings: Carefully follow the AEG manual to set the delay timer. Ensure the current time and desired finish time are entered correctly.
Reset clock: Set the correct time on the cooker if applicable, then reprogram the delay.
Factory reset: Perform a factory reset to clear any corrupted timer settings.
Board replacement: If the timer still behaves erratically, the control PCB or RTC circuit may be faulty and require replacement.
